Operator take does not unsubscribe from its source when it reaches the limit with sync source

[Igorbek]

RxJS version:
master branch.

Code to reproduce:

Observable.create(observer => {
      expect(observer.isUnsubscribed).toBe(false);
      observer.next(42);
      expect(observer.isUnsubscribed).toBe(true); // fails here
    }).take(1).subscribe();

Expected behavior:

Test should have passed.

Actual behavior:

Test has failed.
